scottbit,

Someone took the time to install a 12 volt generator on a '49..pretty neat. Have you made sure you have voltage on the key side of the coil. If the rig was converted to 12 volts, some type of start/run resistor must be hiding in the system somewhere.

If it spins over nicely when starting, and you have spark as you ground a plug wire, then the problem is elsewhere.

If the truck actually died from a lack of fuel, and it just appeared that it was a lack of charge, then you will have to investigate that area.

If you can verify you have spark to the plugs and fuel THROUGH the carburetor into the engine and all this is happening when it is suppose to,(timing), you have narrowed your search. Verify these things first. One might be missing.
